POWER, HEATING, AND VENTILATING APPARATUS FOR BUILDINGS.

SPECIFICATION forming partof Letters Patent No. 576,718, dated February 9, 1897.

Application filed August 29, 1895. Serial No. 560,846. (No modela T0 ctZZ w/mm/ Z Irwin-concern:

Be it known that I, REGINALD PELHAM BOLTON, a citizen of the United States, and a resident of Pelhamville, in the county of l/Vestchester and State of New York, have invented certain new and useful Improvements in Power, Heating, and Ventilating Apparatus for Buildings, of which the following is a specification.

My invention consists of improvements in power, heating, and Ventilating service apparatus for buildings whereby economy is effected in condensing the steam and in feeding the boiler of the power apparatus, also in heating the building by hot air when heating is required, and also in Ventilating the building, as hereinafter described, reference being made to the accompanying drawings, in which- Figure l is a sectional elevation of a building provided with service apparatus in accordance with my invention. Fig. 2 is a sectional elevation of the condensing and heating and Ventilating apparatus on an enlarged scale.

In Fig. l, a represents the boiler for supplying steam for power, heating, and other purposes, said boiler being located in the basement, as usual, for various economical reasons.

-b represents a motive-engine in which some of the steam-power is employed for operating a dynamo c for electric purposes, said engine and dynamo being also located in the basement for certain well known advantages thereof.

e' represents the steam-exhaust pipe of the engine. Itis extended to the top of the build-- ing, preferably Within chimney f of the boilerfurnace. On the roof g, or it may be any other suitable elevated support, is a condensing-coil h, with which the exhaust-pipe e connects for condensing the steam and for utilizing the waste heat of the steam for heating the building in seasons when heat is required.

t' is the discharge-pipe for the water of condensation from the coil. It returns to the basement and connect-s With the hot-Water drum j, from which it is caused to feed into the boiler again through pipe Za by the pressure of the column in return-pipe 1I, which is to be sufficient `to overcome the boiler-pressure. An air-chamber Z in the upper part of the drum] is provided for trapping off the air. m represents a pumpeonnected with the hot-water drum for replenishing the supply of water, as may be required, fromtime to time. The return-pipe t' may connect with t-he suction of the pump m in vcases Where the boiler-pressure is liable to rise higher than the weight of the returning column of Water to utilize the pump toovercome the overbalance of the steam-pressure. l

For cooling the condensing-coil I employ a fan-blower, as u, in suitable connection with the coil and with a Ventilating-flue 0 for Withdrawing the air from the different rooms of the building to cool them and blowing it over the exterior of the coil, or by reverse action to force the heated air from the coil into the rooms to heat them when required, said coil being inclosed in a suitable cover p for causing the best effects on the coil.

The side wall q of the case through which v the hot air escapes from the condenser into the atmosphere overhangs or inclines outward from the bottom upward to fend off the rain from the openings, and the openings are provided with deiector-doors s in Fig. 2, which, being limited in the extent of their openin g to the level plane or thereabout, cast th'e hot air upward when issuing froln them and will be closed by gusts of opposing wind force to prevent back pressure in the venti-I I later.

A valve is provided for admitting air at the top of the condenser-cover when the heated air is to be used for heating the building.

tion. The valve i has a rod u, connected to a crank n, for operating it. The crank may be operated by hand or other means. In this example I represent the fan as geared with an electric motor w for operating it, the motor being connected with the dynamo c by suitable circuit-Wires and a starting-box or rheostat a'. The Ventilating-flue o is connected with the diiferent rooms by suitable'l branch ducts y for distributed effect.

It will be seen that by locating the condenser on the roof in connection Wit-h the power apparatus in the basement by the exhaust-steam and return-water pipes, as de- For obtaining purer air the deilector vvdoors will then close by the effect of the suc- ICO That it may appear clearly that the appa-V ratus acts as a ventilator and a heater two series of arrows are shown-one series formed of unbroken lines to represent the course of foul air from the apartments, the other series formed ot' broken lines to indicate the course of the air to the apartments.

I claiml. In power, heating` and Ventilating apparatus for buildings, the combination of steampower apparatus located in the lower part of the building, a condenser located on or in the upper part of said building, exhaust and rctu'rn pipe connections of said power apparatus and condenser, the fan-blower for the condenser, the iue and branches communicating' between the rooms of the building1 and the cover of the condenser through the fan and the outletand inlet for air to the fan, said fan being' reversible substantially as described.

2. The combination with the eondcnscr,co11 duits communicating between the apartments and condenser, and the fan, of the cover hat ing` the overhangng outlet side and upwardlydeflecting doors to theoutlet-openings, and also having` the inlet-Valve admitting air from the top of the cover substantially as described.

Signed at New York city, in the count)7 and State of New York, this 6th day of August, A. D. 1805.
